BACKGROUND OF THE INVENTION

[0001] (a) Field of the Invention

[0002] The present invention is to provide a steamer with improvedstructure.

[0003] (b) Description of the Prior Art

[0004] Enjoying sauna bath becomes a popular activity for those whowould like to relax themselves after they are off duties. Currently,those who are addicted to sauna bath would go to the public bathingfacility or steam bath or buy a personal steaming box. However, thepublic steam generating system usually includes a boiler associatingwith an electronic control device for controlling the steam output. Thiskind of structure usually has large volume, occupying large space, noteasy to move, and expensive. Usually, it needs a separated room toinstall it. Because of these reasons above, the steam bath so far cannotbe applied for the whole family. It can therefore simply used by oneperson through the steam box. The steam box has large volume, occupyingspace, which is not easy to be stored. It usually has some difficultiesto arrange a free space for installment. Also, the inconvenience thatonly one person can use the steam box at a time is inconvenient for allof the family members, which is the basic flaw.

[0005] Due to the foregoing reasons, the inventor has tried to use themanner of electric heater to generate steam. Even though the effect isgood, it is troublesome to scour the steam generator (or water tank) dueto the scale deposition or poor design for expelling water. Moreover, italso requires a proof not to cause insufficient water supply, whichcannot satisfy the requirement for generating steam, and saving powerconsumption is another requirement, which require for instant solution.

[0006] Another thing is the inventor who also appreciates that thepopular essence therapy can indeed relax our body to achieve thetherapeutic effect. If the essence therapy can be performed togetherwith the steam bath, out body can be effectively released and relaxed,so as to achieve the effect of health activities.

SUMMARY OF THE INVENTION

[0007] Therefore, the inventor under continuous test and design hasprovided an improved steamer (second application) has properties ofsmall volume, no need of change water, fast speed of steam generation,save power, and essence therapy.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] For the purpose of promoting an understanding of the principlesof the invention, reference will now be made to the embodimentillustrated in the drawings. Specific language will be used to describesame. It will, nevertheless, be understood that no limitation of thescope of the invention is thereby intended, alterations and furthermodifications in the illustrated device, and further applications of theprinciples of the invention as illustrated herein being contemplated aswould normally occur to one skilled in the art to which the inventionrelates.

[0017] The improved structure of steamer (second application) canachieve the foregoing beneficial strong points, and the structureincludes a steam body 10, a filter 20, a steam supply unit 30, and acontrol unit 40. As shown in FIG. 1, an upper portion the steam body 10is installed with a holder 101 to hold the filter 20 and a moveablehandle bar 19. When the steam body is to be lifted up, it just simplyneeds to rotate the filter 20 to expose the handle bar 19. A hookinghole (not shown) is formed a back side panel, so that the user can takethe manner to hook in a high level as shown in FIG. 5 or just put it onthe plane.

[0018] The inner structure of the steam body 10 is also shown in FIG. 2.The top portion is installed with an electric valve 11 and electroniccontrol part 12, wherein the electric valve associates with the waterlevel detector 122 to control the input flow of water. The steamgenerator 13 is located at the lower portion, in which the mineral wool14 encloses the steam generator 13. A water input part 16 is located atthe left side, used for controlling the water flowing from the electricvalve 11 to transport into the steam generator 13. A safe valve 17extruding from the steam body 10 is located at right side, used forcontrolling the steam pressure of the steam generator 13 to be at acertain range, so that the steam can be exported to the steam supplyunit 30 through the steam tube 18. If the steam is generated too fastand not being complete exported at the steam supply unit 30, the steamunder overpressure is exported from the safe valve 17, so as to reducethe steam pressure and recover to the normal condition for supplyingsteam. Moreover, an electric heater 15 is installed inside of the steamgenerator 13 and is located at the lower portion, so as to get a betterconvection effect due to the generated heat, a fast rate of steamgeneration, and save of power consumption.

[0019] In the forgoing, in order to maintain the water in the steamgenerator 13 at a certain range, it also includes a water level detector122, separately arranged to have an upper and a lower detection points.Water supply stops when the water level is at the high state, and wateris refilled when water level is at the low state to avoid the issue fortoo much water, which resulting in reduce of steam generatingefficiency. In addition, it can be avoided that when the amount of wateris insufficient, causing evaporation of water to be too fast, affectingthe continuous steaming supplying. Moreover, in order to prevent thewater of the steam generator 13 from being not normally supplied due toa stop of water, clog, or malfunction of the electric valve 11, filter20 or any accidence causing water not being supplied in time accordingto the result of water level detector 122. Consequently, the steamgenerator 13 is continuously heated by the electric heater 15, causingdanger. Because of these problems, a temperature sensor 121 is installedat outside of the steam generator 13 near to th3 electric heater 15, soas to detect the inner temperature of the steam generator 13. Once thesteam generator 13 has no water or has insufficient water, the heater 15continuously produces heat, and causes the abnormal high temperature.The temperature sensor 121 then instructs the control unit to cut thepower, so as to achieve the purpose of save.

[0020] Moreover, in order to prevent the high temperature steam or waterboiling from occurring due to the continuous action of electric heater15 of the steam generator 13, and resulting in a damage or measurementerror of the water level detector 122, a baffle 125 is installed at thewater level detector 122 of the steam generator 13. Also and, a spacingis formed at the lower portion, so that the steam generator 13 isdivided into a steam region X where the electric heater 15 can cause thehigh temperature steam, a low temperature water storing region Y wherethe steam is not directly generated, whereby the water level 122 cansurely work under normal condition and detection capability.

[0021] The external connection part of the electronic control part 12includes a first power line 123 and a second power line 124. The firstpower line 123 can be plugged into a socket, so as to provide power tothe steamer. The second power line 124 is connected to the control unit40, wherein the connecting manner can be a design like the phoneterminal or the plug type, so as to freely disconnect for hoarding andassemble.

[0022] The water used by the steamer is supplied from outside throughthe filter 20. The filter 20 has a water inputting tube 21 forconducting the external water source to the filter 20, and atransporting tube 22 for exporting water to the steam body 10 undercontrol of the electric valve 11. Consequently, the input water can bepurified without producing water dirt. Even after the steam bath, thewater is not necessary to be released. There is no need a conventionalreleasing valve.

[0023] The steam generated by the steam generator 13 is exported fromthe steam tube 18 located at the right side. The steam tube 18 is usedfor connection extension, so that the steam supply unit 30 can belocated at a predetermined location. As shown in FIGS. 1 and 3-4, thesteam supply unit 30has the central free space. One side of the body hasa tube body 35 used to connect the steam tube 18. The steam supply unit30 has a covering body 41, which can be freely open, formed in a form ofbutt hinge 32. A plate body 33 is installed at front of the coveringbody 41, so as to allow the user to conveniently open the covering body41. Several steam holes 34 are formed inner side with respect to a lowerportion of the covering body 41. The steam hole 34 can release the steamthat is input from the tube body 35. The steam hole 34 is designed to belocated at a rather far end relative to the tube body 35. Another sidethen is separated out by the baffle plate 36, resulting in a containingspace 37 near to the tube body 35, so that the containing spacer can beoptionally filled with essence as desired. As the steam is conductedinto the steam generator 30 through the tube body 35, the essence storedin the containing spacer 37 is evaporated due to the effect of hightemperature steam. In this manner, the steam bath and the essencetherapy can simultaneously be performed.

[0024] When the invention of improved structure of steamer is operated,the steamer can be optionally put on a plane or hooked thereon,according to the practical consideration. As shown in FIG. 5, thesteamer is mounted with the hook manner. The steamer of the inventioncan be installed in a public area or the bath rood of a family forconvenient use. In the example of FIG. 5, the second power line 124 ofthe control unit 40 is led to a far lower portion, to ease the user atthe near place for controlling operation of the steam. The steam supplyunit 30 is connected with the tube route at the lower portion. As aresult, the steam and essence can effectively fill the whole room. Theplat body 33, which covered by body 31, is located outside to preventfrom occurring about accident opening by the user, and causing an abruptincrease of steam and an accidental damage. The first power line 123 isconnected to the electric box or a power socket for supply power. Theinput tube 21 of the filter 20 is connected to the water faucet ofexternal water source for supplying water.

[0025] It will be understood that each of the elements described above,or two or more together may also find a useful application in othertypes of methods differing from the type described above.

[0026] While certain novel features of this invention have been shownand described and are pointed out in the annexed claim, it is notintended to be limited to the details above, since it will be understoodthat various omissions, modifications, substitutions and changes in theforms and details of the device illustrated and in its operation can bemade by those skilled in the art without departing in any way from thespirit of the present invention.
